WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 257,835, dated May 9,1882, Application filed March 10, 1881. (N 0 model.)

To all whom it may concern ,Be it known that I, FLAVIUS W. SHELLA-BARGER, of the coiinty of Miami, in the State of Ohio, have invented anew and useful Improvement in ind-Engines, of which the following is afull, clear, and concise specification.

My invention relates to that class of windengines in which the wheel isreversed-4. e., placed with faceside inward toward the derrick-theobject being to have the wind oper- Figure l is aview of the improvedspider or runner, the wheel-hub, and two of the arms or spokes, withtheir vanes pivoted thereon. Fig. 2 is a. longitudinal sectional View ofthe main shaft and a vertical section of the wheel-hub and spider andconnecting-rod, and a view of the eccentric and the main fork orbracket. Fig. 3 is a cross-section through line 1, Fig. 2, with a viewofthe governor-vane also. Fig;4

' is a side view of my invention, showing the action of thegovernor-vane iudotted lines.

My improvementpertains more particularly to those parts which areexhibited in the annexed drawings.

Ais the wheel; B, the'spider or runner, which in this engine is placedupon the hollow shaft E in rear of the wheel A, upon the extreme end ofthe's'ame. '(See Fig. 2.)

O is the bracket or main fork, which supports themain shaft and wheel.

The eccentric D is mounted centrally upon the main shaft, directly overthe pump. It is eased with a circular box or casing, d, which extendspartially over the sides, as shown in the dotted circular line, Fig. 3,is in two parts, and riveted together through projecting ears on theperiphery of the contiguous halves. .An arm, d, extends from the lowerrear edge downward, and is pivoted to pump-lever m near its inner end.This lever is pivoted at its outer end to a side arm, m, of the mainfork at its extremity. It has a spherical case, i, on its inner end, inwhich is a ball, a, with avertical hole through it, in which thepump-rod is suspended. As the lever m is operated through which operatesthe wheel-vanes through the main shaft E. The section 6 of this rodreaches from the extreme rear end to thefront of the bracket, and has aball,g', formed on its front end, which operates in a spherical case, 9,on the rear of the connecting-sleeve This sleeve is pierced centrally atthe front end. with a hole smaller than its internal diameter, and intothis hole the rod f(connecting it with the rock; shaft G, which supportsthe governor-vane) is inserted and secured by the inner and outer nuts,11 and i, on its threaded end. (See Fig. 2.)

The front end of rod f is connected flexibly with the end of an upwardand rearwardly curved arm, p,'of the rock-shaft. The rockshaft ispivoted in the front ends of'the horizontal bars 0, which extend forwardfrom the front limb, 3, of the bracket. (See Figs. 2, 3, and 4.)

The rod f, which supports the governorvane F, is square, is set in therock-shaft with being inclined toward the wheel. llt, however, differsin the vane F being made of a single piece rigidly attached.

A right-angled bar, 70, pivoted at the angle to one side of the frontlimb, 3, connects the governor-rod f with a. wire, h, attached to itsvertical limb, and a chain depending from "its horizontal limb to thefoot of the derrick, through the eyes 6 e e in the bracket and its stem,allows the governor-vane to be operated by hand.

The eyes 0 are cast on the inner front side of the hollow of thebracket. (See Fig. 2, which shows a part broken out to exhibit them.) Toallow the wheel to turn quickly into wind, the spindle S of theturn-table has a semi-cylindricalconcavenicheinitsfrontand rear side just under the shoulder of the bracket. In these niches a cylindricalfriction-roller is pivoted vertically to free the stem at these twopoints from contact with the interior surface of the socket. Thewheel-vanes a are oblong, with the exterior end rounded and the outerangle slightly curved. They are ot'light sheet metal, strengthened by aborder of narrow strap-iron, a, riveted upon the face.

Arms I), of Y shape, made of malleable iron, and cast in a single piecewith the cross-bar b and the eye 0, (through which the wheelarm 0.extends,) are riveted across the inner edge or heel ofthe wing-vanes. soas to strengthen this part. The stem of the Y-sliaped piece b terminatesin a slotted head, and this is connected with the ends of the spokes ofthe spi derby links 0. These latter are short straight rods with an eyein each end. A pivot-bolt connects one end with the arm I) and the otherend is slipped over a tangentialjournal, c, on the tip of thespider-arm. Each vane is in this manner connected to the spider-arm nextin rear of it, as seen in Fig. 1. The terminal 0 has a broad shoulderlike a large rivet-head.

It will be noticed by reference to Fig. 1 that the diameter of thespider B is large in proportion to the size of the wheel-vanes, thelatter being comparatively short. The spider fills the entire open spacefrom the hub to the heel of the wing-vanes, giving increased leverageand easier operation to the governor. The spokes a of the wheelterminate before reaching the ends of the wheel-vanes, which have anoval hole, j, at this point out through them, to allow the straining-rod0 to connect with the thimble or cap on the ends of the spokes, and togive room at this point for'the operation of the vane. Braces ofrod-iron 1" extend from the heel-thimble c, diverging toward the extremity of the wing-vane till they reach points at each edge opposite tothe end of the wheelarm, where they are fastened. They greatlystrengthen the wheel-vanes, and prevent their twisting from a suddengust of wind.

I claim as my improvement 1. In wind-engines having the governor soplaced as to face the wind, the combination of the spiderB on the rearend of the hollow shaft E, having the terminals 0, by which the severalspokes of the spider are each connected with the wheel-vane next inadvance of it, by thelongitudinal movement ofwhich the vanes are turnedinto or out of wind, substantially as shown, for the purpose set forth.

2. Vane-arm b,havingcross-barband thimble 0, and cast in a single piece,whereby the wing-vane is strengthened at the point where it is connectedwith the arm or spoke of the spider B, as shown.

3. In wind-engines, the combination of the centrally-pivoted wind-vanesa, strengthened at their edges by a. border of strap-iron, with thethimble c and brace-rods 0*, attached thereto andto thestrengthenededges,as shown and described.

4. In a, wind-engine having its wheel connected with the governorthrough a hollow main shaft by a rod or its equivalent, the combinationof a ball-and-soeket joint-piece and adjusting-nuts with itsconnecting-sections, substantially as herein shown and specified. In awind-engine, the combination of the arm I), cross-bar I), and thimble0', formed in a single piece, with the vane 60, provided withcentrally-secured brace-rods r and strengthen ingbinding a, as shown anddescribed. a

o. The wheel-vane a, formed with a hole therein, in combination with thecap or thimblej and brace-rods 0, substantially as shown and described.

7. The eccentric strap (1, having the arm d, extending obliquelydownward therefrom, in combination with lever m and arm at and theball-andsockct end joint, n I, as shown and described. 8. In combinationwith fork G and the supporting column,the hollow stem S, having thefriction-rollers n, pivoted in niches formed in its sides, as shown anddescribed.

9. In a wind-engine, the vibrating governor having vane F, twisted stemf, rock-shalt G, rod h, and bell-crank 7c and chain, in combination witharm 19, rodficoupling g g,rod e,'hollow shaft 1), and spider B, as shownand described. R I

10. The combinatioinwiththe automatierockshaft G, curved arm 1 and rod],of the flexible coupling 9 9, rod 6, hollow shaft 1), and spider B, asshown and described.
